Night turned into day, and the revelers rang in a new age of electricity. Edison was thinking way beyond bulbs: He planned an entire grid to carry power from coal generators directly into homes. It took another quarter century for electricity to reach the first 5% of US households—but that proved to be a tipping point. By 1950, the entire country was connected . A similar pattern of adoption—gradually, then suddenly—echoed around the world. Today there’s a new Edison-level transformation under way. It affects how we generate the power that flows to our electrical outlets—and what gets plugged into those zero-emission electrons.
